Used the below code snippet:
#pragma mark - UISearchDisplayController delegate methods
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"SELF contains[cd] %#",
searchText];
[searchResult release];
searchResult = [peopleName filteredArrayUsingPredicate:resultPredicate]retain];
}
